Best practice for configuring probe/gateway Failback has been changed in OMNIBus 7.3.

Failback is an OMNIBus client component feature that allows client to connect back to Primary objectserver after it recovers.

In pre-7.3 versions, the best practice are to configure Server , ServerBackup and PollServer in probe properties file as following:-------------------------------------------Server:"PRIMARY"ServerBackup:"BACKUP"PollServer:60NetworkTimeout:30-------------------------------------------

The reason for above configuration is explained very well in those emails (I am attaching those because some of those emails were deleted from INUG archives) :

In 7.3 this has been changed due to the introduction of Controlled Failback, you are supposed to use following in probe properties file:

--------------------------------------------Server:"VIRTUAL"ServerBackup:""PollServer:0---------------------------------------------Please be advised that above settings rely on detect_agg_gate_resync_complete,disconnect_all_clients and resync_complete triggers. detailed information can be found here:Configuring Controlled Failback of Clients
